TELEPIi-IONE-BOOTH.

Application filed November 24, 1919. Serial No. 340,316.

To all whom it may concern:

Be it known that I, FRANK F. BnnBY, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois,have-invented a certain new and useful Improvement in Telephone-Booths,of which the following is a specification.

My invention relates to improvements in concrete telephone booths, andmore particularly to a concrete telephone booth which is constructed insections, and adapted for economy in manufacture, convenience ofshipment and ease of assembly and repair. It is particularly suitablefor use on electric interurban railway lines where telephones are placedat various points along the way, and where the telephone circuit is bestdisconnectedduring non-use of the booth. The telephone booth isespecially adapted to con struction by the cement-gun process whichconsists of projecting a type of cement commonly called gunite, underpressure against the mold or backing on which it hardens. Further useswill appear from time to time in the course of the specification.

I have illustrated my invention diagrammatically in the followingdrawings:

Figure 1 is an elevation of my telephone booth;

Fig. 2 is a section on the lines 22 of Fig. 1;

Fig. 3 is a section on the lines 3-3 of Fig. 1;

Fig. 4 is an enlarged plan view of my invention with parts in section;

Figs. 5 and 6 are vertical sections of the top and bottom respectivelyofmy telephone booth; I

Fig. 7 is a horizontal partial section through the door, and door jamb;

Fig. 8 is a similar section showing a hinge of the door;

Fig. 9 is a similar section showing details of the door securing means;

Fig. 10 is a detail on an enlarged scale of Fig.

Like parts are represented by like symbols in all the figures. A is acylindrical telephone booth body of reinforced concrete, strengthened attop and bottom by the enlarged rims A A provided with additionalreinforcing, which form horizontal bearing surfaces A A The lowerbearing surface A rests on a base member B comprising a flat circularground engaging rim B and raised central portion B out of contact withthe ground. A peripheral indented ledge B about such raised centralportion is adapted to receive and center the bearing surface of the bodycylinder. On the upper bearing surface A of the cylinder rests a singleintegral roof member comprising a. concave shell C with a ledge or stepC around the interior adapted to rest on the upper bearing surface ofthe cylinder. The periphery or eaves C ofthe roof shell depend, andcenter it on the cylinder. This step is substantially within theperiphery of the roof, and the joint is thus protected by eaves from theweather. The top and bottom of the booth body may be notched as at C(1*, to furnish ventilation at the top and drainage Specification ofLetters Patent. Patented June 21, 1921. I

at the bottom. The booth body is provided the bottom of the cylinder isa floor preferably composed of wooden boards E insulated from theconcrete base by the glass or porcelain insulating members E Castintegral with the cylinder, midway its height, is a step or ledge Fadapted to support a shelf F of wood or other suitable material. Abovethe shelf is the telephone instrument G supported to the interior of thebooth by any suitable means, such as hooks not illustrated. Thetelephone wires may enter'the booth by the porcelain conduit H, or byany other suitable means.

I provide a lock for the door which includes an electrical connectionwith the phone, and a switch adapted to be thrown open when the door isclosed. K is an electric switch, with connections not shown,

which is adapted when. opened to break the door of the booth cannot beclosed and locked without'breaking the telephone c1rcuit;

My method of construction is as follows:

In building the body section, I construct a collapsible cylindricalmold, beveled at top and bottom, and indented adjacent its center, toform the thickened rims and the shelf ledge. About this mold, and spacedtherefrom I place a reinforcement of wire or expanded metal mesh,strengthened at top and bottom in the thickened portion of the mold, bycircular reinforcing bars, or other suitable reinforcement. I leave anaperture the reinforcement for the door, and line it with an angle iron,secured: to the Lying Wire mesh, to form the door jamb. within it, andhinged to it, I place the door frame. VVithin it and secured to'it Iinsert more mesh, leaving a window aperture therein. A tile conduit, isinserted in the upper part ofthereinforcing, to serve as inlet for thewires. When the reinforcement is completed,-I shoot wet'concrete orgunite, as it is called by the trade, projecting it under pressureagainst the mold, from a gun or nozzle, until the reinforcement isincased to a sufiici'ent thlckness. The result is a booth body completedin one operation, the

doorbeing shot at the same time as the body of the booth. The top andbottom are cast V which is easily and cheaply constructed, the

or ,shot separately, and are of the usual re-. inforced concreteconstruction. Waterproof gunite or concrete is used throughout.

Applicant has illustrated an operative mechanism and a practicalway ofmaking it. It will however, be understood that many variations in themethod of manufac ture, and in thearrangement and details of the articleitselfcould be made without departing from the spirit of my invention.

The plunger K could be spring operated, so as automaticaly to reconnectthe switch when the door is opened, and the engagement or connectionbetween the plunger and the switch could be a pivotal instead of acontact engagement, p y

The use and operation of my invention are as follows: 7 s

I provide asmall concrete: telephone booth partsof which can be easilyshipped and handled, are simply assembled, and easily and 'cheaplyreplaced. This avoids thenecessity of complete reconstruction when one.part is broken, whether before assembly, or

after installation. The base of the booth takes its bearing on the soilonly atthe outer edge, and thus furnishes a broad and steady rest,disposing with the necessity of a foundation. The wooden floor in thetelephone booth makes a perfectly insulated surface no short-circuit,for the wooden floor is in sulated from the damp concrete. The provisionof a swltch control by the door insures that the telephone'circuit willnever be connected save when the door is opened and the booth in use.The mere closing and locking of the door isenough to break theconnection.

I claim: M 1. A sectional reinforced concrete booth, comprising acircular base, a circular, hearing surface thereabout, a cylindrical,body section open at top and bottom, said body thickened and reinforcedat the top and bottom, the thickened bottom edge adapted to engage thecircular bearing surface of the base, a circular convex roof section, acircular bearing surface within the periphery thereof, adapted to engagethe thickened up per edge of the body.

2. A sectional reinforced concrete booth,

comprising a cylindrical may open at both ends, an enlarged reinforcedinterior rim about said body at the top and bottom, 8..

bearing surface formed about either end of the cylindrical body, a basesupportingthe bottom of said body, comprising a' flat ground engagingrim, a raised center, and a circular bearing surface thereabout, a unitlid resting on the enlarged top of the cylinder.

In testimony whereof, .I aflix ture in the presence of two witnessesthis 19th day of November, 1919.
